This invention relates to condensers and,

particularly to multi-unit condensers em object of the invention is toprovide a. plu.

rality of condenser units of the straight line type -mounted in a frame,and y means4 actuated by a single knob or dial for'moving the movableplates of each unit into and out of such-units; a further object beingto- -provide a .multiple 'condenser-.off the class*V de,- scribed:wherein the c'( ndenser';.units. are' mounteds'ide'byl side and edge toedge; to form a compact structure which W-illltake up the least amountof,roo'm; and further, in
